At a mall Saturday in Kuala Lumpur, Malaysia, a man writes a message to add to the many hanging there for the people aboard the missing Malaysian jetliner.

A Chinese ship involved in the hunt for the missing Malaysian jetliner reported hearing a “pulse signal” Saturday in southern Indian Ocean waters with the same frequency emitted by the plane’s data recorders, as Malaysia vowed not to give up the search for the aircraft.
